When a plane wave train transverses a medium, individual particles execute a periodic motion given by the equation \[y=5\sin \frac{\pi }{4}\left( 4t+\frac{x}{16} \right)\]where the lengths are expressed in centimeters and time in seconds. Find the phase difference (in degree) for two positions of the same particles which are occupied at a time interval 0.8 s apart.
